A crucifix is seen in the brewhouse of the 'Kloster Andechs' brewery in Andechs near Munich, Germany, April 19, 2016. Germany this year marks 500 years of the so-called Reinheitsgebot (purity law), introduced in Bavaria in 1516 to limit the ingredients used in the beer production to hops, barley and water.
